hey guys last night i made the big mistake of letting my singer set up my stuff for me cuz i was going to be late for the gig. and he pluged both speaker cables in to the same cab. i am running the svt3pro and swr goliath jr and SOB. he went out of both outs onthe amp and in to both jacks of the amp. and me , like and idiot, just asked if it was all set and just pluged in, powered up and played our set. while playing i notice the volume wasn't what it should have been. then as i was breaking down i noticed what6 he did and wondered why i didn't blow something up. what gives??
